Authentication. Policy. Encryption. A complete Security solution from TANDBERG.
TANDBERG Security Advantage
It is now possible to share your organization’s valuable and sensitive information
with more people than ever before. The Internet is a forum for public information
exchange. Extranets provide suppliers and customers access to data that enhances
their productivity. Remote workers have come to expect the same level of resources
as if they were in the office. Innovations such as TANDBERG’s firewall traversal
solution are making it possible to communicate across boundaries.
But, with open communication comes risk. Network administrators cite security
as one of their highest concerns in managing communication tools. Financial
institutions are constantly sharing information that must be restricted. The health
care industry is overwhelmingly concerned with patient confidentiality. The fact
is that any organization needs to protect its information as well as its resources.
TANDBERG is a pioneer in developing solutions to resolve security concerns.
By addressing the issue of security at three levels — authentication, policy
and encryption — TANDBERG provides a complete solution to protect your video
network. TANDBERG helps you keep control over who is using your network
and what they are accessing, and assures adequate levels of privacy.
Secure Conference — Standards-Based Embedded Encryption
Encryption is a
way of scrambling data so that only those who know how to unscramble the
data get access to it. With encryption, you can rest assured that all your video
communication is private. Embedded encryption allows you to enjoy the full
array of features without any degradation in performance, unlike third-party, nonembedded
encryption solutions.
All encryption methods use common algorithms. Security comes from the key, a
number which is passed to the algorithm to tell it how to encrypt the data. A
commonly employed communications encryption method is the “Data Encryption
Standard” (DES). DES works by encrypting data with a 56-bit long key. Triple
DES (3DES) is an enhancement to DES that effectively runs 112-bit long keys.
DES and 3DES are both widely used in commercial and non-defense government
communications today.
To provide a higher degree of security than both DES and 3DES, a new standard
called Advanced Encryption Standard (AES) has been developed. The new
AES standard with 128-bit keys has been approved by the U.S. Government
to protect sensitive, unclassified data and will replace the use of 3DES.
TANDBERG supports all of the following encryption standards: AES, DES, H.233,
H.234 and H.235 with an extended Diffie-Hellman key distribution on H.323,
H.320 and leased lines.
TANDBERG Secure Conference is “on” by default. This automatically generates
an encrypted call, which is indicated with an on-screen lock symbol. A single
lock symbol is displayed for DES. A double lock symbol is displayed for AES.
Secure Conference DES and AES are both available in point-to-point calls and
multipoint calls on ISDN and IP up to 768 kbps on the full TANDBERG product
line. TANDBERG’s implementation of the AES and DES cryptographic algorithms
has been validated as conforming to Federal Information Processing Standards
(FIPS) by a laboratory accredited by The National Institute of Standards and
Technology (NIST).
